Preferred embodiment
The present embodiment determines which kind of rank user uses in browsing pictures according to the photographed scene relevant information of picture
Amplification experience, different amplification factors is set for different pictures.
When determining scene brightness relevant information, the main light luminance for considering shooting picture is bright and clear when shooting,
Picture can be easy to obtain the details of current scene, picture seems more fine after shorter exposure in this way
It is bright-coloured, and when light is inadequate, picture needs more exposure, simultaneously as the working principle drawn game of camera camera chip
Limit, can improve luminance gain, obtain the more normal picture of brightness with this, certainly will will lead to noise in this way and be equally amplified,
And when rear end carries out effect optimization processing to picture, such influence cannot be completely eliminated, thus picture can be shown after amplification
It is coarse to obtain some.Different scene captures goes out different pictures, also has corresponding embodiment in picture storage information, such as outdoor
The picture of shooting, the universal time for exposure is shorter, and ISO value is lower, and a kind of YUV (colour coding method) compression of images is at JPEG
The memory space that (a kind of Standard of image compression) occupies afterwards also can be bigger than normal, conversely, the photo lithography of indoor shot is generally longer,
ISO value is also higher, and the memory space occupied after JPEG after compression of images also can be relatively small.Meanwhile the shooting of selection point
Resolution can also have larger impact to picture, and resolution ratio is bigger, and picture detail is more when showing on the terminal device, can amplify
It is bigger, when resolution ratio is smaller, once amplification tends to obscure.
For example, knowing when user is when outdoor has taken some sunny, bright scene pictures by the technology
The amplification factor of picture one or more ranks, in this way use Wei not be promoted into terminal display behind outdoor optical line charge toe ring border
Family is when amplifying display it can be seen that more details.When user has taken some indoor scenes in dark environment, by
In these scene darks, noise is more, and image quality is not fine and smooth enough, and at this moment user recognizes bat by the technology in browsing
After taking the photograph picture quality category insufficient light environment, by the amplification factor control of picture in a certain rank, avoids amplification too many, lead to figure
Piece seems Rough Fuzzy.
Principle of being taken pictures under different scenes according to the above camera and the analysis of picture compression technology, the embodiment of the present invention pass through exposure
Between light time, ISO value determine current shooting environment, in conjunction with photo resolution, occupy memory space and determine needed for picture
Amplification experience rank.In the EXIF information that the information as used in these shootings is stored on picture when picture saves,
Therefore, it is possible to analysis directly is read out to the EXIF information of picture, magnification level when determining browsing.Above-mentioned detailed process is as schemed
Shown in 4, including step S401 to step S406:
S401 obtains the time for exposure of image, and determines its corresponding first amplification coefficient according to the time for exposure.
The step can obtain the time for exposure of present image with as shown in figure 5, in implementation process, then by the exposure
Time is compared with each time for exposure section, which time for exposure section is belonged to determination, and further determine that its is right
Determining amplification coefficient is finally set to the time for exposure corresponding amplification coefficient by the amplification coefficient answered.
S402 obtains the ISO value of image, and determines its corresponding second amplification coefficient according to ISO value.
The step can obtain the ISO value of present image with as shown in fig. 6, in implementation process, then by the ISO value with
Each section ISO is compared, which section is belonged to determination, and further determine that its corresponding amplification coefficient, finally will
Determining amplification coefficient is set to the amplification coefficient of ISO value.
S403 obtains the resolution ratio of image, and determines its corresponding third amplification coefficient according to resolution ratio.
The step can obtain the resolution ratio of present image with as shown in fig. 7, in implementation process, then by the resolution ratio
It is compared with each resolution ratio section, which resolution ratio section is belonged to determination, and further determine that its corresponding amplification
Determining amplification coefficient is finally set to the amplification coefficient of resolution time by coefficient.
S404 obtains the storage size of image, and determines that its corresponding 4th amplification is according to storage size
Number.
The step can obtain the storage size of present image, then should with as shown in figure 8, in implementation process
Storage size is compared with each section, to determine which storage section belonged to, and further determines that its is corresponding
Determining amplification coefficient is finally set to the amplification coefficient of storage size by amplification coefficient.
S405 calculates the magnification level of image according to four above-mentioned amplification coefficients.
During S405 is executed, the amplification factor of image can be obtained according to following calculation formula: magnification level X=
w1*a+w2*b+w3*c+w4*d.Wherein, a, b, c, d are respectively the corresponding amplification coefficient of each EXIF information, w1、w2、w3、w4It is each
Weight proportion shared by EXIF information, these ratio values can be obtained by a large amount of practical applications.
After reading EXIF information, the amplification factor of corresponding picture is obtained and calculated, so that it may according to different pictures
The amplification factor of picture is adjusted, different details experience is presented for user.
Determining magnification level is applied in the display of image by S406.
Certainly, those skilled in the art can also pay the utmost attention to the resolution sizes of the picture in picture EXIF information, expose
Between light time, ISO value, different amplification display levels is divided according to different levels, and be aided with occupy memory space determine it is final
Magnification level.
The embodiment of the present invention fully takes into account the picture in different scenes shooting there are the difference in image quality, browses in user
Specific factor is uniformly amplified to when experience, cannot take into account it is all, thus for the picture of varying environment shooting using different clear
It lookes at amplification effect, provides the user with better visual effect experience.Relative to traditional picture browsing mode, this programme is being detected
Information needed for picture both is from the information saved in picture, independent of the camera applications of a certain characteristic, either comes from
Picture on mobile phone, digital camera or internet directly reads relevant information and then detects in this technology after Loading Image
Adaptive amplification picture afterwards, speed is fast, and effect is good, it is easy to accomplish promotes.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
